Well, dancing might be too strong a word for it. But some booties were definitely shaking.

The group’s name, subject to varying pronunciation, is a straightforward reference to its origins. First came Daft Punk, a French electronic dance music duo. Among their credits is the score for the recent movie “Tron: Legacy,” so if you’re not familiar with their sound, that might be a handy shorthand. Tron party music. Then along came New Orleans musician and producer Earl Scioneaux III, aka the Mad Wikkid, who decided to take Daft Punk’s synthetic, computer-driven, futuristic compositions and feed them to a Crescent City brass band.

Brassft Punk opened its set with little fanfare on Saturday, letting their distinctive fusion of two seemingly alien genres speak for itself. Which it clearly did: Over the course of the next hour, the audience in the Boom Boom tent steadily swelled from several dozen to several hundred people.

The Madd Wikked handled the computer-synthesizer-programmed track side of the spectrum, while five other musicians weighed in with drums and horns. Over the course of the set, they illustrated that they cover a spectrum of sound, not merely a simple formula.

The opening number emphasized that irresistibly funky New Orleans second-line feel. Then through the middle of the set, the band skewed things more toward the techno side, with the Madd Wikked and saxophonist Khris Royal, sometimes playing an electronic wind instrument, dominating the vibe. There wasn’t quite as much dancing, but the unorthodox renditions of Daft Punk compositions drew regular applause.

Finally, as the end of the set neared, the New Orleans flavor reasserted itself with more tuba on the stage, more gyration in the audience, and a sense of true musical fusion. It was capped off by some on-stage dancing from a rather motley quartet of costumed characters who seemed to symbolize some truly weird futuristic second-line voodoo.

As the show ended and patrons wandered back out into full daylight, this much was already clear: It wasn’t going to be just another day at the beach.
